Abelard to Apple
The vast majority of American college students attend two thousand or so private and public institutions that might be described as the Middle--reputable educational institutions, but not considered equal to the elite and entrenched upper echelon of the Ivy League and other prestigious schools. Richard DeMillo has a warning for these colleges and universities in the Middle: If you do not change, you are heading for irrelevance and marginalization. In Abelard to Apple, DeMillo ar
La France a-t-elle encore une identité géographique ? / Armand Frémont
Texte de présentation de la conférence
L’identité de la France est un objet obscur. Le territoire national avait trouvé son aboutissement à la frontière physique. Aujourd’hui la solidarité, la socialité et l’être ensemble ne se définissent plus uniquement par référence à une étendue spatiale continue sur laquelle s’exerce la souveraineté de l’État-national. Les frontières qui se dessinent à travers les réseaux sociaux ou la conscience partagée d’

Accompagner les enseignants et les équipes pédagogiques après les évaluations des enseignements
Les expériences montrent que mettre en oeuvre une démarche d’évaluation des enseignements sans prévoir de mécanismes d’amélioration n’est pas
Cette présentation aura un double objectif :
(1) proposer une réflexion sur la mise en place et l’adoption par les enseignants et les étudiants de la démarche d’évaluation et
(2) présenter des modalités d’accompagnement aux enseignants ou aux équipes pédagogiques suite aux éva

Seismic Waves
The first site for this Topic in Depth comes from the Department of Geological and Mining Engineering and Sciences at Michigan Technological University and is called What Is Seismology? (1). The site describes the basics of seismology, the various types of waves associated with it, and even contains a link that shows you how to make your own P and S waves. Next is the Earthquakes Overview site (2), provided by The Tech Museum. Visitors can explore topics such as seismographs and waves through an
Simple Machines
This series of three interactive, multimedia activities introduce and demonstrate the properties of six simple machines. Specifically, the lessons show how levers, pulleys, inclined planes, screws, wheels and axles, and wedges can reduce the amount of work done by humans. After learning about the characteristics of each classification, users can try to find the simple machines that make up a lawn mower. By inspecting the mower from different angles, several simple machines are revealed and must
Next Generation Space Telescope (NGST) Observatory Architecture and Performance
Although not scheduled to be launched until 2011, design plans for the Hubble Space Telescope's replacement are already underway. This research paper describes some of the architectural and performance specifications slated for the Next Generation Space Telescope (now called the James Webb Space Telescope). The seven-meter primary mirror will be hexagonal and made up of twelve smaller one-meter mirrors, allowing the observatory to see "objects 400 times fainter than seen from large groundbased t
University of Wisconsin - Madison: Todar's Online Textbook of Bacteriology
Authored by University of Wisconsin bacteriology professor Kenneth Todar, this online textbook is geared towards college and advanced high school students studying general microbiology and medical bacteriology. The primary sections of the text include: Bacterial Relationships with Animals, Principles of Bacterial Pathogenesis, Bacterial Diseases of Humans, and General Bacteriology. Within these sections links are provided to a wealth of information about growth of bacterial populations, importan
ORNL: Robotics and Energetic Systems Group
The Robotics and Energetic Systems Group at Oak Ridge National Laboratory (ORNL) conducts research in Robotics, Energy Transformation Systems, Power Transfer Devices, and Human-Amplifying Machines. A full description and related factsheets are posted for each research area. The group's work spans the spectrum from basic research to "one-of-a-kind integrated system design, development, test, and evaluation" in robotics. Other areas of research address approaches to heat storage and release system
Monterey Bay Aquarium: Live Web Cams
The Monterey Bay Aquarium Web site offers a great set of live Web cams offering views of marine life in Aquarium exhibits and the nearby ocean. The Web cams also serve as "a gateway to information about ocean habitats and conservation topics." Visitors may view live footage between 7 a.m. and 9 p.m. Pacific Time from a penguin cam, kelp cam, otter cam, Monterey Bay cam, and outer bay cam. The Web site also includes pre-recorded footage of feeding shows -- a nice alternative if the live cams are
Protect Those Eyes
Students design and build prototypes for protective eyewear. They choose different activities or sports that require protective eyewear and design a device for that particular use. Students learn about the many ways in which the eyes can be damaged and how engineers incorporate different features and materials into eyewear designs to best protect the eyes.
Building Tetrahedral Kites
Working in teams of four, students build tetrahedral kites following specific instructions and using specific materials. They use the basic processes of manufacturing systems – cutting, shaping, forming, conditioning, assembling, joining, finishing, and quality control – to manufacture complete tetrahedral kites within a given time frame. Project evaluation takes into account team efficiency and the quality of the finished product.
Who’s Down the Well?
Students learn about several possible scenarios of contamination to drinking water, which comes from many different sources, including surface water and groundwater. They analyze the movement of sample contaminants through groundwater, in a similar way to how environmental engineers analyze the physical properties of groundwater to predict how and where surface contaminants travel.
Engineering in Reverse!
Students learn about the process of reverse engineering and how this technique is used to improve upon technology. Students analyze push-toys and draw diagrams of the predicted mechanisms inside the toys. Then, they disassemble the toys and draw the actual inner mechanisms. By understanding how the push-toys function, students make suggestions for improvement, such as cost effectiveness, improved functionality, ecological friendliness and any additional functionality they determine is an improve
Oceans, climate and weather
What is the difference between weather and climate? What do the oceans have to do with them? Weather is the day-to-day state of the atmosphere and its short-term (minutes to weeks) variation. Climate is typically described by the regional patterns of seasonal temperature and precipitation over 30 years. The averages of annual temperature, rainfall, cloud cover, and depth of frost penetration are all typical climate-related statistics. The oceans influence the worlds climate by storing solar ener
The Relationship between Science and Technology
In this lesson, Students will discuss the technology(ies) that powers satellites and enable(s) them to move through space. They will be introduced to the concept of “attitude control” and the role technology has in the design of spacecrafts, as well as engage in an angular momentum experiment.
Factory Farms and Organic Alternatives
Modern farming has helped feed the world, but along the way, the land has suffered, according to this video adapted from the series Race to Save the Planet. When farmers grow too much too fast, topsoil is depleted. Farmers can work around this problem with fertilizers, irrigation, and pesticides, but these create new problems. Pesticides can harm wildlife, linger on fruits and vegetables, or wash into water supplies. Farmers are now finding new approaches to raising food, like diversifying crops
